Neodymium(III) sulfide is a inorganic chemical compound with the formula Nd2S3[2] composed of a two neodymium atoms in the +3 oxidation state and three sulfur atoms in the -2 oxidation state. Like other rare earth sulfides, neodymium(III) sulfide is used as a high-performance inorganic pigment.[3]
Preparation
Neodymium(III) sulfide can directly be produced by reacting neodymium with sulfur:[4][5]
- 2Nd + 3S → Nd2S3
It can also be produced by sulfidizing
- Nd2O3 + 3 H2S → Nd2S3 + 3 H2O
Properties
Neodymium(III) sulfide is (as γ-form) a light green solid. The compound comes in three forms.
Neodymium(III) sulfide has a high melting point and a lot of polymorphic forms which make it difficult to grow.
